WHAT IS AGO?
´
Replaces ALL Operators
« In
operation for 24 months at ADF-C & BP
« Over 140,000 contacts supported automatically
« Automated Schedule Generation & Deconfliction
« Automated Ground Resource Allocation &
Monitoring
« Automated Spacecraft Monitoring & Contact Plan
Execution
« Automated Personnel Notification

AGO HISTORY
´
In 2006, BP was directed to develop a fully
automated system
« High
risk program
« Maximize cost savings
« Prove it can be done
AFSCN incorporated automated pre-pass
procedures to support this effort
´ Since then it has been adapted to more than
15 satellites at BP

RESOURCE ALLOCATION
´
´
´
´
Hardware Architecture supports dynamic
component allocation (no fixed hardware strings)
Inference Engine deconflicts and matches highest
priority, functioning equipment to a contact
Future allocations predicted (look ahead)

CONTACT MONITORING
´
Monitors system for proper:
Configuration – Pre-pass Resource allocation
« Setup – Configure hardware & software
« Telemetry - % collected vs. % expected
« Commanding - % successful vs. % attempted
« Plan execution - tasks completed vs. total tasks
² at – (t1et + t2et …tnet) > (x)%
« Shutdown – Deconfigure hardware & software
« Post-pass – Data processing & dissemination
«

SPACECRAFT MONITORING
€
Derived status equations:
› Logical
› Mathematical
› Mission rules & constraints
€
Database defined logic determines
satellite & subsystem health

CONTINUOUS MONITORS
´
Software
«
3 types of software monitored
Constant – Always running
² Transient – Comes up & down with each contact
² Cron Table
²
´
Hardware
«
Interrogated at least every 20 seconds
Ack/Nack response & configuration validation
² Daemons monitor CPU’s, disks, memory, etc.

Proper execution = Event
Non-Critical component failures = Warning
Critical component failures = ERROR

OBSERVATIONS
´
´
´
Reduced Costs – No recurring costs for 4 shifts of
operators
Decrease in overall system errors
Resolves human related problems
«
«
«
´
Every task executed on time, every time
No improvising
No Human Error
Lacks human related ingenuity
«
«
Can’t adapt dynamically
Every task executed on time, every time

“LIGHTS OUT” EXECUTIVE
´
LO is designed to:
«
«
´
´
´
Do what the operator would do
NOT do anything unauthorized
² AGO executes files written by Spacecraft & Ground System
Engineers
² Detects errors and Initiates files to take corrective action
² Files send whatever commands are necessary including safing the
vehicle
² Notify engineers of the status
Each mode is selectable by individual spacecraft and
ground system
Scoring for Hardware, Software, Contact, Spacecraft
Selectable Automatic notification via text message,
email, and/or pop-up

NEXT STEPS
´
AFSCN automation required for non-Nxx
systems
« 22
SOPS on board
« Test plan development is progress
« Testing will start this 1st Quarter FY10
Real-time status to AFSCN
´ More sophisticated scheduling algorithms
´
« Dynamic
scheduling modifications
« Priority adjustments
